Premier African Minerals Ltd (AIM:PREM, OTC:PRMMF) told investors it will today begin the second phase of the plant test at the Zulu lithium and tantalum project in Zimbabwe.
The company aims to reach a steady state of operation and maintain plant availability of 22 days per month.
"At present the OEM and Zulu personnel are conducting inspections, normal maintenance, and a minor change to flow control in the spodumene float section in advance of this second test run,” said chief executive George Roach.
“Some operating parameter changes and the possible reintroduction of an additional reagent successfully used in 2024, to the extent necessary, round out the preparations.
“Our expectation remains that this will see another major step forward in the optimisation process."
